Emerald Ash Borer Quarantine and Regulatory Information
Emerald ash borer (EAB) is a serious invasive tree pest, and consequently a quarantine has been placed to help slow the spread of EAB to other areas in Minnesota (Emerald Ash Borer status map).
These are considered regulated articles by the MDA:
- Ash logs
- Ash tree waste
- Ash chips and mulch
- All firewood (non-coniferous)
Emerald Ash Borer Quarantined Counties
The Minnesota Department of Agriculture (MDA) has confirmed EAB in new areas of Carlton County and in several counties for the first time (Meeker, Murray, Otter Tail and Wadena). There are now 58 counties in the state with known EAB infestations. The MDA has enacted a quarantine to limit the movement of firewood and ash material into Minnesota and out of infested counties. The MDA issues quarantines for all counties known to have EAB to reduce the risk of further spreading the tree-killing insect.
A virtual informational meeting for residents and tree care professionals is planned for Tuesday, July 8 from 10 a.m. -11 a.m. Follow this link to register for the meeting.
The public can provide input and comment on the proposed emergency quarantines before they are formalized. The MDA is taking comments on the proposed formal quarantine now through August 8, 2025, and recommends adopting the quarantine on August 11, 2025.
Comments can be made during the virtual meeting or by contacting:

No regulated articles are legally allowed to be moved into Minnesota without the written approval and the proper documentation provided to the Commissioner of Agriculture.
No regulated articles are legally allowed to move outside of a quarantine (untreated or treated), unless they are accompanied by a MDA certificate. MDA Certificates are only available when a Compliance Agreement (CA) is signed between the Minnesota Department of Agriculture and the company, city, county, agency, or organization interested in moving the regulated article.
A CA is a written agreement between a person and a regulatory agency to achieve compliance with regulatory requirements. For more information about CAs please visit our Frequently Asked Questions or contact via Report A Pest.
